A radiometer sonde has been constructed to observe radiation from the atmosphere above the radiometer in the spectral region 5–7 μ with a spectral resolution of about 0·3 μ. The results from a flight of the instrument at night up to a height of 25 km are presented. Emission from water‐vapour indicates a dry stratosphere with a mass mixing ratio of about 3 × 10 −6 . An energy flux originating above 25 km amounting to about 2 μW cm −2 has been observed near 5·7 μ. Various possible sources for this additional radiation are discussed.
